Chapter 4 - the emergence of action Flashcards
reflex
an innate response that occurs automatically to a particular form of stimulation
patellar reflex
an early-emerging reflex, also known as the “knee jerk reflex,” involving the extension of the lower leg when the tendon at the knee cap is abruptly pressed
rooting reflex
a reflex found in newborns in which a gentle touch on the results in movement of the face as to bring the mouth around the touching object
grasp reflex
a reflex found in newborns in which they will grasp an object when it is pressed against their palm
stepping reflex
a newborn reflex of engaging in repetitive stepping motion when held upright
moro reflex
a reflex found in young infants in which an abrupt lack of support of the head results in an outward and upward movement of the arms
maturational account
an account of development in which developmental change is largely attributed to biological maturation as opposed to experience
motor deprivation
a condition under which an organism is either prevented from moving or not given the opportunity to pair movement with perception or objects acted upon
dynamic systems theory
a theory of motor development that stresses the importance of the physics of the limb and the environment in which an action is made in addition to central cortical control programs
perceptual-motor development
development that proceeds through an integration with perceptual feedback. While normally discussed with respect to vision, it can also apply to other modalities
prereaching
mostly failed attempts to touch objects by very young infants
visual flow fields
the streaming visual patterns made by objects and terrain over time as they flow by an observer who is either moving or is having the environment move about her
affordances
the possibilities for action based on the properties of the objects or surfaces on which the action will be performed. The same object may have different affordances for different organisms
mirror neuron
a neuron in the brain that is activated both when performing an action and when perceiving it being performed by others and that is thought to support imitation
imprinting
a form of learning that takes place during a critical period in which young members of a species acquire a behavior or response patterns that remains permanent after the critical period is over
